What Is a Business Line of Credit?

Contents:

A lot of business owners assume a line of credit is just a loan with a different name. It isn’t, and that misunderstanding costs people money every year through interest they never needed to pay.

A business line of credit is a flexible pool of funds you can draw from as needed, up to an approved limit, paying interest only on the amount you actually use. Once you repay what you’ve borrowed, that credit becomes available again, much like a credit card.

Why That Distinction Actually Matters

A term loan hands you a lump sum upfront, and interest starts accruing on the full amount immediately, whether you use it all or not. A line of credit sits available until you need it. If your business faces a $15,000 gap in cash flow for six weeks, you draw exactly that, pay it back, and stop paying interest — no lump-sum commitment required.

How a Business Line of Credit Works in Practice

Lenders approve a credit limit, often between $10,000 and $250,000 depending on business revenue and credit history, then let you draw funds via check, transfer, or a linked card. Interest rates in 2026 typically range from 8% to 24% APR depending on the lender and your creditworthiness, with online lenders generally charging more than traditional banks in exchange for faster approval.

“Owners who treat a line of credit like free money get into trouble fast,” says Renee Falk, a small business lending advisor with over a decade at a regional credit union. “The businesses that use it well treat it strictly as a cash flow bridge, not a way to fund growth they can’t otherwise afford.”

When a Line of Credit Makes Sense

  • Covering seasonal cash flow gaps between busy and slow periods.
  • Bridging payment delays when clients pay invoices 60-90 days out.
  • Handling unexpected repairs without draining reserve cash.

Seasonal Timing Matters

Retailers often draw on a line of credit heavily from September through November to stock inventory ahead of the holiday season, then repay it during the January-February sales rush. Landscaping and outdoor service businesses frequently see the opposite pattern, drawing funds through slower winter months and repaying once spring and summer bookings pick up.

When It Doesn’t Make Sense

A line of credit isn’t the right tool for financing large, one-time purchases like equipment or real estate, where a term loan usually offers a lower fixed rate. It’s also risky for businesses without predictable revenue, since unpaid draws can compound quickly at higher interest rates than most term financing.

FAQ

Is a business line of credit hard to qualify for?

Requirements vary, but most lenders want at least six months in business and $25,000+ in annual revenue for approval.

Does a line of credit affect my credit score?

Yes, especially if the lender requires a personal guarantee, in which case utilization and payment history can appear on your personal credit report.

What’s the difference between secured and unsecured lines of credit?

Secured lines require collateral like inventory or receivables and typically offer lower rates; unsecured lines don’t require collateral but often carry higher interest.

Can a new business get a line of credit?

It’s possible but harder; many lenders require at least six months to two years of operating history first.

Bottom Line

A business line of credit shines as a flexible safety net for short-term cash flow needs, not as a substitute for long-term financing. Understanding that difference upfront saves owners from paying interest they didn’t need to.
